5(4c−2d)+2d−6(d−3c). Distribute: =(5)(4c)+(5)(−2d)+2d+(−6)(d)+(−6)(−3c) =20c+−10d+2d+−6d+18c. Combine Like Terms: =20c+−10d+2d+−6d+18c =(20c+18c)+(−10d+2d+−6d) =38c+−14d.

Hi

<span>5(4c-2d) + 2d - 6(d-3c) = 20c - 10d + 2d - 6d + 18c

5(4c-2d) = 5(4c)+5(-2d) = 20c-10d
- 6(d-3c) = -6(d)-6(-3c) = -6d+18c


</span>20c - 10d + 2d - 6d + 18c = 20c + 18c - 10d - 6d + 2d = 38c - 14d

20c+18c = 38c
-10d-6d+2d = -16d+2d = -14d

Answer: 38c-14d

(2/3) / -14 is the same as (2/3) * -(1/14) since we can multiply by the reciprocal when dividing with fractions.

2/3 * -1/14 = -2/42 = -1/21

A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:
rate = 36 miles / 45 min = 0.8 miles per mindistance traveled = 0.8 miles per min ( 60 min ) = 48 miles
Hope this answers the question. Have a nice day.
